Encrypt or decrypt text with AES-GCM using a password-derived key (PBKDF2 + SHA-256, 100k iterations). All crypto runs locally via the Web Crypto API — your text and password never leave the browser.
Used to derive the AES key via PBKDF2 (SHA-256, 100k iterations)
Read-only — fixed parameters
Text to encrypt
AES-GCM provides authenticated encryption — tampering with the ciphertext will cause decryption to fail. The output bundles salt + IV + ciphertext + auth tag, so you only need the password to decrypt.
